Procedure
N-(4-bromo-3-methyl-5-isoxazolyl)-2-biphenylsulfonamide was prepared in the same manner as described in Example 8b from 5-amino-4-bromo-3-methylisoxazole and 2-biphenylsulfonyl chloride in 71% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 145-147° C.
